Abstract The high quality of the services provided is a component that determines the competitiveness of laboratories. It is necessary to update laboratories in modern conditions of the development of scientific and technological progress. Another important task is to ensure control of the quantitative content of toxic elements, the introduction and application of fast and reliable methods of their analysis. Analysis of monitoring the quantitative content of toxic elements in food samples confirms the need for analytical express control; its implementation allows tracking the content of potentially hazardous elements in products and preventing their influence on human health. The analysis of monitoring results for 2017-2019 showed the predominant ranges of toxic elements’ concentrations in various categories of products. It was revealed that when the quantitative content of cadmium is detected, the maximum number of test results falls within the range of less than 0.001 mg/kg. In the case of the quantitative content of lead detection, the maximum number of test results falls within the range of less than 0.01 mg/kg; in the case of detecting arsenic, the range is less than 0.02 mg/kg.
